Tomtom Rider review
 

http://www.webbikeworld.com/r3/tomtom-rider/

Quite in depth, but not particularly glowing review (dubious battery life, very particular on/off switch, no battery life indicator).

Having said that, the last paragraph seems a tad odd in that the reviewer doesn't seem to know much about GPS (i.e. he/she was expecting it to be able to trace the route taken), as well as stupid complaints (expecting locally-used names as opposed to official road names).

Anyone with a Rider care to comment?
